Description

200818138 IX. Description of the Invention [Technical Fields of the Invention] The present invention relates to an information recording apparatus capable of recording or reading digital data, and more particularly, in relation to a data recording surface of an information recording medium such as a compact disc An information recording device that performs label printing on the label side of the side (printed surface such as text or video). [Prior Art] For example, a disc recording medium having a recording capacity of several Mega Bytes or a number of Giga Bytes, such as a CD (Compact Disk) or a DVD (Digital Versatile Disk), is used as a storage mechanism. After being transported to the inside of the apparatus, a device that chucks the spindle motor and reads or reads data by means of an information recording means such as an optical head equipped with a lens is known, and is generally used. use. Moreover, recently, BD (Blu-Ray Disk) or HD-DVD (Hi gh D efi ni ti ο n D igit al V ers at i 1 e D isk ), which can be recorded at a high density, has the same basic structure. However, a disc medium having a recording capacity of 5 times to 10 times or more higher than a conventional medium such as a DVD has been developed by shortening the wavelength of the light source or increasing the NA (Numerical Aperture) of the lens. When the information recording device such as the optical disk device using the information recording medium capable of high-density recording of the optical disk medium or the like is increased, the amount of recorded data is also increased, and once the number of information recording media that have been recorded is -5 - 200818138 Add, it is not easy to manage these information recording media that have recorded huge information. In this regard, there are several methods for displaying management information of information recording media such as optical disc media on media such as optical discs. For example, Patent Document 1 describes a method of recording information on a recording surface of a disc by allowing the management information of the optical disc medium to be visually recognized. Specifically, a method of recording using laser light of an optical pickup in another field of information recording in a recording surface of a optical disk is disclosed. Further, the character or image corresponding to the information recorded on the information recording medium can be printed on the label side opposite to the recording surface of the information recording medium such as a compact disc. Specifically, for example, printing is performed on the surface of the optical disc label using an ink jet printer or the like which can print a label. In addition, some of the optical disc devices in which the ink jet print head is assembled and become a printable label have been put into practical use. The optical disk device which is such a printable label is a method of performing label printing on a rotating optical disk by mounting a print head on the optical disk device (see, for example, Patent Document 2), or a optical disk device in which a printing function is incorporated (for example, Patent Document 3) and the like are proposed. In the optical disk device described in Patent Documents 2 and 3, the print head is movable on the radial axis of the optical disk. [Patent Document 1] Japanese Laid-Open Patent Publication No. 2004-280953 (Patent Document 2) Japanese Patent Publication No. 2002-812140 (Patent Document 3) Japanese Patent No. 3 3 4 1 5 7 2 [Abstract] -6- 200818138 [Problems to be Solved by the Invention] However, in the optical disc device described in Patent Documents 2 and 3, when a movable print head is provided on the radial axis, when the label is printed, the print head is drawn. Through the center of rotation of the disc, it will come into contact with components such as the chuck. Therefore, the movable range of the printing head, that is, the printing area is narrow, and it is difficult to perform printing near the inner circumference of the disc, and there is such a problem. Further, when it is desired to perform full printing or the like, the printable area is narrow due to the above reasons, so label printing takes a lot of time and there is such a problem. In addition, in consideration of miniaturization of the entire information recording device such as a disc device, it is necessary to arrange the printing head or the closing of the printing head at the rear of the device (on the opposite side to the discharge side of the disc), so that the replacement of the printing head is necessary. Disassembling the upper cover of the device, etc., the maintenance of the device is very troublesome, and there is such a problem. Accordingly, the present invention has been made in view of such a problem, and its object is to make it easy to print in the vicinity of the inner circumference of an information recording medium such as a disc in an information recording apparatus capable of performing label printing while recording or reading digital data. The printing can be performed at high speed, and the maintenance of the device can be easily performed. [Means for Solving the Problem] In order to solve the above problem, according to one aspect of the present invention, an information recording apparatus can be provided which is inserted by an information recording medium such as a compact disc, and the information recording medium is inserted before being inserted. The information recording device such as a disc device that can perform label printing is characterized in that '200818138 has: an information recording means, such as an optical pickup on the recording surface side of the information recording medium; and a print head, which is relatively At the position opposite to the information recording means on the information recording medium, label printing is performed; and the printing head moving means is such that at least a part of the printing head is offset from the center of rotation of the information recording medium. The radial direction of the recording medium moves in parallel. In this way, by the printing head moving means, the printing head is caused to move in a direction parallel to the radial direction at a position shifted by the rotation center of the information recording medium such as the optical disc, thereby causing the printable area to be increased, and the information recording such as the disc is caused. Printing near the inner periphery of the media can be easily performed. Further, by increasing the printing area and printing the label surface of the information recording medium such as a compact disc in this manner, the printing time can be greatly shortened and the printing can be performed at a high speed. Here, the information recording device may further include a chuck that is provided on the same side as the print head with respect to the information recording medium, and holds the central portion of the information recording medium; The print head is moved at a position that does not interfere with the chuck. Further, in the above information recording apparatus, the print head moving means may move the print head to the retracted position; and in the retracted position, the head cleaning mechanism for performing the cleaning of the print head and the head for performing the print head may be provided. The closing means of the closing cover; the cleaning and closing of the printing head by the means is performed at a position away from the information recording means. In the present invention, since the print head can be moved to a position deviated (biased) from the center of rotation of the information recording medium, the member such as the optical pickup that does not interfere with the radial axis can be closed or The cleaning machine-8-200818138 is disposed on the front side of the device more than before, so that the information recording device can be miniaturized. Further, in the above information recording device, the print head moving means may be configured such that when the print head is moved to the information recording medium, the print head is moved in the radial direction parallel to the information recording medium, and is printed. When the head is ran away from the information recording medium, the print head is moved to a predetermined direction different from the radial direction, and then moved to the retracted position. Further, the print head may be provided with an ink discharge portion on the opposite side of the label surface of the information recording medium, and the ink discharge portion may be disposed in a direction parallel to the radial direction of the information recording medium. The plural of the ink is spit out. Further, the information recording device may be further provided with a loading means for inserting or discharging the information recording medium; and the printing operation of the information recording medium by the loading means may be used to perform the label printing. In this way, especially in the case of printing the text information of the data room, the printing time can be shortened and the convenience of the user can be improved. That is, by the action of the loading means, the printing time when the printed material is small can be greatly shortened. Further, in the above information recording apparatus, the print head may be detachably provided to the information recording apparatus main body; and the print head moving means may be such that the print head is displaced from the rotation center of the information recording medium. The opening moves toward the opening provided on the discharge side of the information recording medium. At this time, for example, by providing an openable and closable cover for replacing the print head to the upper opening, the print head can be replaced on the front side of the apparatus without disassembling the upper cover of the information recording apparatus. Therefore, even if the upper -9-200818138 side of the information recording apparatus has no space, it is not necessary to pull the information recording apparatus out of the repair as before. Further, the above-described information recording device may further include a loading means, and has a tray for placing the information recording medium; and the tray is provided with a maintenance member for performing maintenance of the print head. The term "maintenance member" as used herein refers to, for example, a member that closes the print head or a waste ink adsorber that first absorbs waste ink during air injection. According to the above configuration, in addition to simplifying the configuration of the information recording apparatus, the maintenance of the apparatus can be facilitated, and the convenience of the user can be improved. At this time, the maintenance part can be detachably provided to the tray. For example, a function of closing the print head or a waste ink adsorber for adsorbing waste ink during air jet is detachably mounted at the rear of the tray. According to the above configuration, in order to take out the apparatus for taking out the information recording medium, the maintenance member such as the cover or the waste ink adsorber can be detached and cleaned, so that contamination inside the information recording apparatus can be further prevented. Further, the print head is disposed in a field in which the field of the information recording medium is divided along the moving direction of the information recording and recording means, and is located in the information recording medium in relation to the rotation direction of the information recording medium. It is ideal in the field of the downstream side of the means. According to the configuration described above, the ink discharged from the printing head and suspended in the ink jet flow to the side surface side of the information recording apparatus casing due to the air flow generated by the rotation of the information recording medium, thereby preventing the information recording means such as the optical pickup or the like from being located. The substrate or the like behind the device is contaminated. Further, the print head may be provided with an ink discharge portion on the opposite side of the label of the information recording medium on the label -10-200818138; the ink discharge portion has a radial direction perpendicular to the information recording medium. A plurality of ink discharge ports arranged in the direction of the direction. At this time, it is also possible that the above-mentioned information recording apparatus is a more suitable loading means for inserting or discharging the information recording medium; and the label printing is performed by the discharge operation of the information recording medium by the loading means. Moreover, the head control unit may be provided to control the printing head moving means so as to change the moving distance of the printing head once; and the head control unit changes the moving distance of the printing head once. A single printing mode in which the same field on the information recording medium is printed once and a multiple printing mode in which the same field on the information recording medium is printed plural times is selectively set. In this case, the upper head control unit may control the printing head moving means such that the first moving distance of the printing head is 1/ti (n is a natural number) of the maximum printing width of the printing head. Moreover, it may be further provided with: a head cleaning mechanism for cleaning the upper print head, and a recording means cleaning mechanism for cleaning the information recording means; the head cleaning mechanism and the recording means cleaning mechanism are integrally formed . In this case, it is also possible to provide maintenance parts for maintenance of the print head, and the head cleaning mechanism and the recording means cleaning mechanism and the maintenance member are integrally formed. At this time, the information recording apparatus may further include a maintenance control unit for controlling the cleaning of the information recording means after the head cleaning mechanism cleans the print head. [Effect of the Invention] As described above, according to the present invention, the information recording print head which can perform label printing at the same time as the digital data record -11 - 200818138 or read is moved to the rotational position of the information recording medium such as a disc. So that the print head does not touch the components such as the chuck, the area is wider than before, so that the line near the inner circumference of the disc or the like. Further, since the printing area is widened, the printing time can be greatly shortened even when entering, and high-speed printing is possible. Further, according to the present invention, the rotation center of the information recording medium such as printing is shifted from the discharge side of the position information recording medium (the replacement of the print head of the information recording apparatus, etc., and thus the excess space is different from the previous one.

The label printing portion L7 mainly includes: a print head 750; and a print head driving mechanism for moving the printing head 75 0 in the radial direction; and a print head maintenance for closing or cleaning the printing head 75 0 0 means. The print head 705 is configured such that the center of the optical disc 5 (or the chuck 730) is disposed on the side opposite to the front side (the front panel 714 side) of the optical disc device 70, and is also provided in the optical The pickup 740 is opposite to the optical disk 5 (on the label side of the optical disk 5), and is movable along the radial axis R (that is, in the radial direction of the optical disk 5). Further, an ink ejecting portion 750a is provided on the lower surface side of the printing head 705 (the label surface side of the optical disc 5), and the printing head 75 0 is moved toward the outer circumference or the inner circumference of the rotating optical disc 5 on the radial axis. At the same time, ink is ejected from the ink ejecting portion 250a, whereby the label surface of the optical disc 5 can be label printed. The print head 705 is held by three sides by a slightly C-shaped print head holder 725, and is mounted on the head support plate 754. On the upper side of the head support plate 754, two head drive bearing members 75 6 are provided on the left and right sides of the print head 75 0. Each of the head drive bearing members 759 is provided with a bearing (linear bearing) 756a that penetrates in a direction parallel to the radial direction. Further, the two head drive shafts 7 5 7 which are disposed in parallel (parallel to the radial direction) are provided through the inner circumferences of the two bearings 756a which are arranged in the radial direction. The two head drive shafts 7 are inserted. The two ends of the 5 7 (the end of the front panel 7 1 4 side and the end of the rear panel 7 1 6 side) are respectively supported by the same shaft support 17-200818138 holding member 75 8 . The print head drive mechanism mainly includes a head drive motor 760, a ball screw 762 coupled to the head drive motor 760, a bearing 764 through which the ball screw 762 is inserted, and a link connecting the bearing 764 and the head support member 754. The member 766, the support head drive motor 760, and the drive mechanism support member 768 of the ball screw 762 are constructed. The head drive motor 7 6 0 ' rotates the ball screw 7 6 2 by its power. The ball screw 762 extends in a direction parallel to the radial direction. The bearing 746 is configured to be movable in a parallel direction in the radial direction by the rotation of the ball screw 762. The coupling member 766 connects the bearing 764 and the head supporting member 754, and the head supporting member 754 can be moved in the parallel direction in the radial direction in accordance with the movement of the bearing 764. The drive mechanism supporting member 786 supports the coupling portion of the head drive motor 760 and the ball screw 762 and the tip end portion of the ball screw 762. Further, the shaft support member 75 8 and the drive mechanism support member 76 8 are attached to a plate-shaped support member provided on the upper portion, which is not shown. The print head maintenance means includes a closed lid accommodating portion 770 for accommodating the lid 772 and the waste ink absorber 774. The closing cover 772 is for suppressing the drying of the printing head. In the printing standby, the ink discharging portion 75 0a of the printing head 750 is covered by the closing cover 772. Further, the waste ink adsorber 774 is, for example, a printing error such that the ink discharge portion 250a is prevented from being clogged and the ink is not ejected, so that air is not mixed into the printing head and the air is sprayed. A place where ink is ejected from the ink discharge portion 75 5 a regardless of printing. The cover 772 and the waste ink adsorber 774 are housed in the closed cover -18-200818138 portion 770, which is disposed on the side opposite to the optical disk device 700 on the opposite side to the discharge side (the exit side) of the optical disk 5 (back) Panel 71 6 side). In the label printing portion L 7 of the optical disk device 7 having the above configuration, once the ball screw 7 6 2 is rotated by the rotation of the head driving motor 760, the bearing 764 is radially along the ball screw 762. Move in the parallel direction of the direction. Since the bearing 764 is coupled to the head support plate 7 54 via the coupling member 766, the head support plate 754 moves in the radial direction in accordance with the movement of the bearing 764. At this time, the inside of the head drive bearing member 759 is provided in the head support plate 753, and the head drive shaft 757 is inserted through the bearing 715a, so that the head support plates 754 are mutually connected. The two head driving shafts 757 provided in parallel with the radial direction are guided, and are linearly movable in the parallel direction in the radial direction. Here, since the print head 75 0 is disposed on the radial axis R toward the center thereof, the movement of the head support plate 754, that is, the movement of the bearing 764, can be directed to the optical disk on the radial axis. The inner circumferential direction and the outer circumferential direction are free to move. Thus, in the prior optical disc device 700, the print head 75 0 is moved on the radial axis R. However, the center portion of the optical disc 5 is provided with the chuck 73 0. Therefore, if the printing head 705 moves on the radial axis R, it may come into contact with the chuck 703. Therefore, in order to avoid such contact, the print head 75 0 cannot be moved to the vicinity of the inner circumference of the optical disc 5 (around the opening 5a), as shown in Fig. 6, the printable area is narrow in the previous optical disc device 700. It is difficult to perform label printing near the inner circumference of the optical disc 5, and there is such a problem. That is, if the previous optical disc device 700 is used for label printing, since the print head -19-200818138 7 50 cannot move to the vicinity of the inner circumference of the optical disc 5, as shown in the printing example of FIG. 7, on the optical disc 5 The field W near the inner circumference (around the opening 5a) is not printed smoothly. In addition, printing on the label side of the optical disc 5 is performed by converting the original information to be printed into polar coordinates. For example, in the case of the printing example of Fig. 7, in the case where the entire surface of the optical disk 5 is to be subjected to flat printing or the like, since the printable area is narrow as described above, the time required for printing increases, which causes such a problem. On the other hand, in order to avoid such a problem, a print head driving mechanism that can move the print head 750 in the radial direction of the optical disk 5 (the movable direction of the tray 720 that transports the optical disk 5) is provided, since the head drive Since the print head driving mechanism such as the motor 760 is larger than the width of the optical disc 5, the overall width of the optical disc device 700 becomes large, which also causes a problem of an increase in size of the apparatus. Therefore, among the optical disc devices 100, 200, 300, 400, 500, and 600 according to the first to sixth embodiments of the present invention described below, it is intended to be easily printed on the label side of the optical disc 5 to be recorded. The information corresponding to the data in the disc 5 not only makes the management of the optical disc medium easy, but also makes it easy to print near the inner circumference of the optical disc 5, and can even print at a high speed even when performing full printing, or repair the device. It is easy to carry out, and the movable range of the print head is changed to a position deviated from the radial axis R. Hereinafter, the optical disk devices 100, 200, 300, 400, 500, and 600 所述 according to the first to sixth embodiments of the present invention (the configuration and operation of the optical disk device 1 according to the first embodiment) will be described in detail - 20-200818138 First, the configuration of the optical disc device 100 as an example of the information recording apparatus according to the first aspect of the present invention will be described with reference to FIG. 8 and FIG. 9.

One end of the shaft 1 5 7 for the head drive (the end of the panel 1 1 4 side), Attached to the inside of the device of the front panel 1 14; The other end of the shaft 1 5 7 for the head drive (the end of the rear panel 6 6 side), It is mounted on the same shaft support member 丨5 8 of the rear panel 1 16 〇 The print head moving means is mainly composed of: Head drive motor 160,  Ball screw 1 6 2 which is connected to the head drive motor 160 Ball nut 1 64 that is passed by the ball screw 1 64 a connecting member 166 that connects the ball nut 1 64 and the head support member 1 5 4 , The ball screw support member 168 is provided in the middle of the ball screw 164.  Head drive motor 1 6 0, The ball screw is turned 16 2 by its power. The ball screw 162 extends in a direction parallel to the radial direction. The ball nut 164 is configured to be movable in a parallel direction in the radial direction by the rotation of the ball screw 162. Connecting part 1 6 6, Attaching the bead nut 164 to the head support member 1 5 4 With the movement of the ball screw 164, Can make head support part 1 54, At a position deviated (biased) from the center of rotation of the optical disc 5, Moving in the radial direction parallel to the ball screw support member 1 6 8 It is a piece that supports the ball screw 62. Is supported by a ball screw support plate 1 6 8 A, Bearings are built in (not shown in the middle of the line, the front part is inserted and inserted in the middle of the roll cap) -25- 200818138 Ball screw support unit 168B, 168C made. In this embodiment,  Ball screw support unit 1 6 8 B, 1 6 8 C is integrated. The ball screw 162 is a ball screw support unit 168B, After the 168C is inlaid through the bearing, It is concluded by a nut or the like which is not shown.  also, The optical disk device 1 in the present embodiment can move the radial direction of the print head 150. For example, it is controlled by an limit sensor (not shown) or the like. Here, Limit sensor, Is the part used to control the printing area, Ideally set up, At least the ink discharge portion 150a of the print head 150 is at a position that can reach the peripheral portion on the back side of the optical disk 5. By setting the limit sensor in such a position, When the print head 150 prints the label side of the disc 5, Wide printable area, Printing near the inner circumference of the optical disc 5 is facilitated.  Print head maintenance means, A cover accommodating portion 1 70 for accommodating the lid 1 72 and the waste ink absorber 1 74 is provided. Closed cover 1 72, Used to suppress the drying of the print head, In the printing standby, The ink discharge portion 15 0a of the print head 150 is covered by the lid 172. also, Waste ink adsorber 174, For example,  In order to prevent the ink ejection portion 250a from being blocked and the ink from being ejected, a printing error occurs, It is a place where air is not mixed into the printing head 150 to be ejected (the ink is ejected from the ink ejecting unit 150a regardless of the label printing). The cover accommodating portion 1 7 〇' in which the cover i 72 and the waste ink adsorber i 74 are housed is disposed on the side opposite to the optical disk device 100 on the side opposite to the discharge side (the exit side) of the optical disk 5. (Rear panel 1 1 6 side).  Here, Referring again to Figure 10 and Figure 1, Different from the previous one,  The print head 150 does not run onto the radial axis. Therefore, the cover accommodating portion 170 including the cover 1 72 and the waste -26-200818138 ink adsorber 174, It is also configured to be offset (offset) from the radial axis. therefore, Even if the optical pickup 140 moves along the radial axis toward the rear side of the device, Nor does it contact the optical pickup 1 40 with the closed lid housing portion 170. Therefore, the cover accommodating portion 1 70 can be disposed closer to the front side of the device than before. The length of the optical device 1 径向 in the radial direction can be shortened. that is, The disc device 100 can be miniaturized.  In the label printing portion L1 of the optical disk device 1A having the above configuration,  Once the ball screw 1 62 is rotated by the rotation of the head drive motor 160,  Then, the ball nut 164 moves in the radial direction along the ball screw 126. Since the ball nut 1 64 is coupled to the head support plate 154 through the coupling member 166, Therefore, the head support plate 154 cooperates with the movement of the ball nut 164. On the other hand, the position deviated from the center of rotation of the optical disk 5 is moved in the radial direction. at this time, The inside of the head bearing member 1 56 is provided on the head support plate 1 54. It is inserted through the shaft 157 through the bearing 156a. Therefore, the head support plate 1 54 is guided by the two head drive shafts 1 57 which are disposed parallel to each other in the radial direction, On the other hand, the position deviated from the center of rotation of the optical disk 5 can be linearly moved in the parallel direction in the radial direction. also, Print head 1 500 Different from the previous one, Is configured such that its center will be biased toward the radial axis R. Therefore, it can be accompanied by the movement of the head support plate 1 5 4 ,  That is, the movement of the ball nut 1 64, At a position offset from the radial axis R, In a direction parallel to the radial direction, The inner circumference and the outer circumference of the optical disc 5 are freely moved.  also, The print head 150 is configured, The field containing the optical disc 5 is divided into two fields which are divided by the moving direction of the optical pickup 140 (that is, the radial direction - 27 - 200818138 axis R in the present embodiment). In the field of the downstream side of the optical pickup 140, with respect to the rotational direction of the optical disc 5, More ideal. therefore, In this embodiment, If the disc 5 is rotated clockwise in Fig. 8 or Fig. 9, Then, the print head 150 is arranged in the right field which is divided by the radial axis R, More ideal.  This is because, Suspended ink spouted from the print head 150 Although it travels toward the outside of the optical disc 5 due to the air current generated by the rotation of the optical disc 5, However, if the print head 150 is offset from the upstream side of the optical pickup 1404 (the left side of FIG. 8 and FIG. 9 with respect to the radial axis R), The suspended ink can easily reside on the side of the optical pickup 140. The reason is that the optical pickup 140 is contaminated. on the other hand, If the print head 150 is disposed offset from the downstream side of the optical pickup 140 (the right side with respect to the radial axis R in FIGS. 8 and 9), Then, since the ink flows toward the side panel 1 18,  So for example, An ink absorber or the like is provided on the side panel 1 18, It is possible to prevent contamination of the optical pickup 140, Easy to recycle floating ink (ink mist).  Here, Based on Figure 1 2 and Figure 13, The operation and effect of the optical disc device 100 according to the present embodiment will be described. In addition, Fig. 12 is a view for explaining comparison between the printable area when the optical disk device 7 00 is used and the printable area when the optical disk device 1 of the present embodiment is used; (a) when using the previous disc device 700, (b) A case where the optical disk device 100 according to the embodiment is used. also, Fig. 13 is an explanatory view showing a printing example when the optical disk device 100 described in the embodiment is used.  As shown in Figure 12 (a), In the previous optical disc device 700, Since the print head 705 moves on the radial axis R, Therefore, in order to avoid inadvertent contact with components such as the clip 730 - 200818138, Cannot move to the inner circumference of the disc 5, As mentioned above, Printing near the inner circumference of the optical disc 5 is difficult (Fig. 6). But at the same time, As shown in Fig. 12(b), the optical disc device 1 of the present invention is disposed in the 'and previously different' print head iso, Will pass the rotation center of the disc 5, The position shifted (biased) from the radial axis R of the radial path of the optical disk 5 is moved toward the position where the center comes forward. therefore, Since the print head 1 500 does not touch parts such as 1 3 0, Therefore, the printing area can be widerned than before. According to the optical disc device 100 according to the embodiment, Then, it is possible to print the vicinity of the inner circumference (the area W around the opening 5a). E.g, As shown in Figure 13. Even when printing on the label side of the disc 5, Also using the same as the previous optical disc device 700 shown in FIG. 6, According to the optical disc device 1 according to the embodiment, Then, the pattern W can be printed in the field W near the inner circumference of 5. also, If the optical disc device 1 according to the configuration is Then, by expanding the area as described above, Even when the label side of the disc 5 is completely printed, Also shorten printing time, High speed printing.  also, In the optical disc device 100 according to the embodiment, The discharge operation of the optical disc 5 caused by the loading means 1 20 of the optical disc device 100 being inserted into the optical disc device 100 can also be performed. To print labels.  As shown in Figure 14, In the case where only the text information recorded in the disc 5 is recorded, When the discharge of the optical disc 5 from the optical disc device 100 is performed (Fig. 14 is the discharge of the optical disc 5 (the direction is indicated by E), Control the print head 150 to discharge the ink. (Refer to the configuration, it is aligned parallel. Available in and chucks. Therefore, it is easy to carry out the operation of the optical disc 5, and the optical disc can be used in a large capacity according to the actual wide printing. For example,  The front side of the eject) is printed -29- 200818138 text information, The printing result as shown in Fig. 14 can be easily obtained.  That is, in this embodiment, Since the print head 150 is disposed at a position offset from the center of the optical disc 5, Therefore, the tray 120 moves the optical disk 5 toward the outer periphery thereof in order to discharge the optical disk 5 to the outside of the optical disk device 1', Thereby, the print head 15 5 can be relatively moved to the optical disc 5. Therefore, If the print head 150 is printed on the optical disc 5 once or plural times, the information such as characters or graphics can be printed. The label printing can be performed by the discharge operation of the optical disc 5. In addition, On the occasion of the discharge of the disc 5, Whether or not the print head 1 50 is activated, As long as the print head 150 is moved in the opposite direction to the discharge direction of the optical disc 5, Even if the print head 1 50 is not operated, It can also be printed at high speed.  also, The printing example shown in Fig. 14, As a print head 1 50, A plurality of nozzles are arranged in a parallel direction in the radial direction of the optical disc 5 (for example, 300 to 400 are arranged side by side in a row or two in a gap of 40 // m).

The closing cover 272 and the closed lid accommodating portion 274 in which the waste ink adsorber 274 is housed, The rear side of the optical disc device 200 on the side opposite to the discharge side (the exit side) of the optical disc 5 (the rear panel 2 16 side) is provided.  Here, The print head 250 does not run onto the radial axis. Therefore, the lid accommodating portion 270 including the lid 272 and the waste ink adsorber 274 is Also configured to be offset (offset) from the radial axis, Therefore, regarding the miniaturization of the optical disk device 200, The same as the case of the optical disk device 100 described in the third embodiment.  The above has been described with respect to the configuration of the optical disc device 200. But from -35- 200818138 based on Figure 17A and Figure 17B, The operation of the label printing unit L2 having the light 2 of the above configuration will be described. In addition, Fig. 17B shows a state in which the inside of the optical disk device 200 according to the second embodiment is in a state in which the print head 250 is printing a label.  Figure 17A is a diagram, The print head 250 runs to the retracted position to wait. If you start from this state, The bead screw 262 rotates by the rotation of the head drive motor 260, Then, the ball nut 264 moves in the radial direction along the ball screw. The ball nut 264 is coupled to the head drive bearing member 256 via the connection 266. Therefore, the head driving member 25 6 cooperates with the movement of the ball nut 264. And moving in the radial direction at a position where the optical disc 5 is deviated. at this time, The inside of the bearing member 256 to be set, It is inserted through the shaft 25 7 through the bearing 25 6a. Therefore, the head drive bearing member 256 is guided by the two head drive shafts 25 7 provided in the radial direction, and is moved linearly in the radial direction at a position shifted from the center of rotation of the optical disk 5. Furthermore, Print head 25 0, It is coupled to the head drive bearing member 256 through the head support portion. Therefore, the movement of the print head 250 and the ball nut 246 is coordinated. The position shifted by the center of rotation of the optical disc 5 moves in the parallel direction in the radial direction.  Here, Print head 2 5 0, Different from the previous one, The center is configured to be offset from the radial axis R. Therefore, the movement of the head drive bearing member 256 can be That is, the ball nut 2 6 4 , At a position offset from the radial axis R, Parallel to the radial direction, The inner circumference and the outer circumference of the optical disc 5 move freely.  Dish device, the invention,  The shape of the machine makes the roller 262 and the component are rotated by the bearing. And the direction of the direction 254 is the direction of departure to make it accompany the movement -36- 200818138 More specifically, The print head 250 is offset from the radial axis, As shown in Figure 17A, Print head 250, The line can be moved at a position that does not interfere with the chuck 203 or the optical pickup 240 (in Fig. 17A, the dotted line is pulled in parallel with the radial direction at a position offset from the chuck 230 or the optical pickup 240,  It is indicated that the print head 250 is located at a position to the right of the dotted line).  also, The print head 250 is configured, In the two fields in which the field including the optical disc 5 is divided along the moving direction of the optical pickup 240 (that is, the radial axis R in the present embodiment), Relative to the direction of rotation of the optical disc 5, in the field of the downstream side of the optical pickup 240, More ideal. therefore, In this embodiment, The disc 5 is rotated clockwise in Fig. 16 or Fig. 17A, etc. Then, the print head 250 is arranged in the right field which is divided by the radial axis R, More ideal.  This is because, Suspended ink spouted from the print head 250 Although it travels toward the outside of the optical disc 5 due to the air current generated by the rotation of the optical disc 5, However, if the print head 25 is offset from the upstream side of the optical pickup 240 (the left side in FIG. 16 and FIG. 17A with respect to the radial axis R), Then the suspended ink will easily reside on the side of the optical pickup 240. The pollution optical pickup is 2,400. on the other hand, If the print head 250 is offset from the downstream side of the optical pickup 240 (the right side of the radial direction R is shown in FIG. 16 and FIG. Then, since the ink flows toward the side panel 2 1 8 , So for example, An ink absorber or the like is disposed on the side panel 2 18,  It can prevent contamination of the optical pickup 2 4 0, Easy to recycle floating ink (ink mist) ° Then, As above, In this embodiment, The radial direction of the print head 250 -37-200818138 The movement in the parallel direction, It is controlled by the limit sensor 29 1 . That is, The print head 250 is moved toward the front side of the device. As shown in Figure 7B, The limit sensor shutter 292 is located in the recess 291a' of the limit sensor 291, and the limit sensor shutter 292 blocks the light passing through the recess 291a. in this way, The light receiving element of the limit sensor 291 cannot receive light from the light emitting element. Thereby, the print head 250 can be controlled from moving further toward the front side of the apparatus.  Here, in the example above, Although an example in which the print head 250 is always linearly moved in the parallel direction of the radial direction is explained, But the print head 250, It is not always necessary to move in a direction parallel to the radial direction as long as it can move without interference with the chuck 230 or the optical pickup 240. only, In order to enable the printing of the label on the optical disc 5 to be performed at a high speed, The print head 250 can also be, During at least the movement on the disc 5, Moving in a direction parallel to the radial direction of the optical disc 5, After running away from the disc 5, it moves in a direction that is not parallel to the radial direction. An example of the movement of such a print head 250 This will be explained based on Fig. 18. In addition, Fig. 18 is an explanatory diagram showing an example of the movement trajectory of the printing head 25 0 described in the second embodiment of the present invention.  As shown in Figure 18, The print head 250 is assumed to move at the position of (A) (the position where the print head 250 is a solid line) or the position of (B) (the position indicated by a dotted line at the position of (A)). Label printing. in this way, Print head 250, When label printing is performed on the disc 5, the printable area can be increased. From the point of view of high-speed printing, Ideally, At least linearly move on an axis parallel to the radial axis R. but, Print -38- 200818138 Brush head 25 0, Once the system runs away from the disc 5, Move to the position where the brush is not being applied (for example, moving from the position of (B) in the figure to (C when setting), Then the print head 250 does not necessarily need to move linearly.  It is also possible to move in a direction not parallel to the radial axis R.  that is, Print head 250, When not printing labels, it is placed in the middle, Carry out maintenance such as cleaning, Or to prevent the ink discharge portion 25 0a from being closed, But the retreat position, It is not necessary to position (contact) a member such as an optical pickup (not shown) that moves on the radial axis R. therefore, The retracted position is preferably not as close as to the side near the outer periphery of the optical disc 5 (near the side panel 2 1 8 side). Therefore, it can also be configured as When the print head 25 0 moves from the disc 5 to the retracted position, It can be more outward than when printing labels, Move in a direction that is not parallel to the radial axis R. In addition,  Easy label printing or printing speed, etc. Then, even if the print head 250 is on the disc 5, As long as it does not interfere with the components such as the clamping table 230, It does not have to be linearly transported on the axis parallel to the radial axis R. The specific mechanism required for the traversing print head 250 shown in Fig. 18 is illustrated based on Figs. In addition, Figure 1 is a perspective view showing the configuration of the optical disk device according to a modification of the embodiment; Figure 1 is a perspective view showing the main part of the optical disk device shown in Figure 19. Fig. 2 is a plan view showing the constitution of the optical disk device. In addition, the same configuration as that of the second embodiment will be omitted.  As shown in Figure 19 to 2, The upper part of the print head 250, a print head holder 2 9 6 that is configured to hold the print head 250 The position of the print head label) is even in the center of the interference, such as drying, etc. If you think about being in the light, you can move it.  Trace to move this implementation 2 〇 1 1 diagram of the invention useful retainer -39- 200818138 2 96 above, A print head guide pin 296a for guiding the movement of the print head 25 is provided. also, At print head holder 296, A through hole (not shown) through which the side surface penetrates in a direction perpendicular to the radial direction is provided by the through hole.

The head is traversing the shaft 297, One end is embedded in a through hole 298a formed in the first shaft support member 298, The other end is mounted on the second shaft support member 299. The second axis support member 299, It is a part of a slightly L-shaped type. It is mounted on the head drive bearing member 256.  also, To cover the field of movement of the print head 250 from above the device,  A print head guide disk 295 is provided. The length of the print head guide disk 295 (the length in the direction parallel to the radial direction), The system and the head drive shaft 257 are substantially the same, The width of the print head guide disk 29 5 (width perpendicular to the radial direction), The length of the tether support member 258 is substantially the same. The print head guide 295, There is a print head guiding groove 295a for guiding the movement of the printing head 25 0, By fitting the print head guide pin 296 in the print head guiding groove 295a, Print head 250, Guided by the print head guiding groove 295a, Moving along the print head guiding groove 295a. In this variation, The printing head guiding groove 2 9 5 a is attached to the optical disc 5, Formed in a straight line parallel to the radial direction, The predetermined position on the outer side of the outer circumference of the optical disc 5 is bent at a predetermined angle, It is formed linearly in a direction non-parallel to the radial direction.  therefore, Print head 25 0, Guided by the print head guiding groove 295a,  When moving to the disc 5, it moves in a direction parallel to the radial direction.  After running outside the disc 5, Then moving in a direction non-parallel to the radial direction -40-200818138 L2 setting cap shifting disk structure system structure Fig. 9 Figure tnzr ink printing motion Next, Referring to Figures 17A and 17B, The operation of the label printing unit of the optical disc device 200 according to the second embodiment of the present invention will be described. As shown in FIG. 17B, Ball nut 264, On the front side of the disc 200, After moving to the portion where the ball screw support member 268 is located, it is locked at this position. The print head 250 is movable to a position corresponding to the locking position of the ball screw 246. therefore, The print head 250 can be moved from the position shown in Fig. 17A to the position shown in Fig. 17B. The ink is ejected from the ink discharge portion 250a while moving, Thereby, the light 5 can be label printed.  then, Based on Figure 22 to Figure 25, For example, the print head 250 according to the second embodiment of the present invention is described.

Fig. 24 (b) is a squint of the constitution of the cleaning mechanism according to the embodiment: Fig. 25 is a perspective view showing the printing head 250 and the closing cover 272 according to the embodiment.  As shown in Figure 22 and Figure 23, Below the print head 25 0, A water cover 272 and a wiper 28 such as an example of a cleaning mechanism are provided. In addition, About the brush head 2 50, Print head holder 2 5 2 Head support substrate 2 5 4, Head drive bearing parts 2 5 6, The composition of bearing 2 5 6 a, As already mentioned above,  Detailed description is omitted here.  -41 - 200818138 Print head holder 2 5 2 is as described above, It is inserted through two head lifting shafts 2 52a which are arranged side by side in the direction parallel to the radial direction. The upper portion is fitted to the two through holes 254a formed in the head supporting substrate 254. The head support substrate 254 is fixed to a fixing screw (not shown). In a through hole (not shown) through which the head raising/lowering shaft 252a of the head holder 2 52 is inserted,  There are 2 linear roller bearings 252d embedded in the system. Limiting the movement of the head lifting shaft 252a in the horizontal direction, It can only move in the vertical direction. also,  On the side of the print head holder 252, A guide pin 252b is provided. When the print head 250 moves, The guide pin 252b is disposed on the guide rail 276 extending in the direction parallel to the radial direction on the side of the print head 25 0. The movement of the print head 25 is thereby guided.  also, The end of the guide rail 276 on the rear side of the optical disc device 200, It is formed with an inclined surface 276a. When the print head 250 is closed, First of all, The guide pin 2 52 is moved along the upper surface of the guide rail 276 in the direction parallel to the radial direction toward the rear side of the device. With this, The print head 25, which is held by the print head holder 252, also moves toward the rear side of the apparatus in a direction parallel to the radial direction. then, By the guide pin 252b moving obliquely downward along the inclined surface 276a of the guide rail 276, The print head 250 that is held by the print head holder 252 is also moved obliquely downward. The ink discharge portion 250a is closed by closing the lid 272. Here, The guide pin 252b is moved obliquely downward along the inclined surface 276a of the guide rail 276. The head drive shaft 257 is used to guide the movement in a direction parallel to the radial direction. The movement in the vertical direction is guided by the head raising and lowering shaft 25 2a.  In addition, The print head holder 25 2 is formed with a long hole 252c in a direction parallel to the radial direction of -42 - 200818138 in the longitudinal direction thereof, The long hole 252c is used to supply ink to the ink tube 278 of the print head 250. Ink tube 278, The ink groove portion 251 (see FIG. 15) is connected in a free shape and is connected thereto. Referring to Figure 25, The configuration of the print head 250 and the cover 272 will be described. As shown in Figure 25 (a), An ink supply hole 250b is provided on the upper surface side of the printing head 25 0. The number of ink supply holes 250b, In this embodiment, it is one, because it is a monochrome example. But if it is colored, it is blue, Magenta, 3 of the yellow, Or add 4 to black.  also, As shown in Figure 2 5 (c), The lower side of the print head 250, And the ink supply hole 250b is connected, Along the longitudinal direction of the printing head 25 0 (in the present embodiment, it is a direction parallel to the radial direction), An ink discharge portion 250a is formed. The ink discharge portion 250a, There are nozzles (ink discharge ports) arranged in parallel directions in the radial direction of the optical disc 5. The closing cover 2 7 2 ′ is configured to prevent the ink from the ink discharging unit 25 0a from drying out. Instead, the printing head 250 can be closed by covering the ink discharging unit 250°.  also, As shown in Figure 25 (b), The closing cover 272 has a slightly rectangular parallelepiped shape. On the upper side (printing head 250 side), A head accommodating portion 272a, which is a recess for accommodating the ink discharge portion, is formed. In addition, As shown in Figure 23, In the closing cover 272 of the present embodiment, a hollow is formed on the back side of the bottom of the head receiving portion 272a. The bottom surface of the closure 272 is open. also, The closing cover 272' must be disposed at a position far from the rear of the optical pickup 240 in order to avoid interference with the printing head 250 and the optical pickup 240. However, if the optical disk apparatus 200' according to the present embodiment is movable at a position offset from the radial axis R, the print heads 250-43 - 200818138 are moved. Therefore, even if the closing cover 272 is not disposed at a position far from the rear of the optical pickup 240, Therefore, the size of the rear side of the optical disc device 200 can be reduced.  then, Except for Figures 22 and 23, Also add Figure 24, The configuration of the cleaning mechanism described in the embodiment will be described. The cleaning mechanism described in this embodiment, By a wiper 2 80 that moves in a direction perpendicular to the radial direction,  And its drive mechanism.  Scrape 280, There is a wiping head 280a at its tip end. The wiping head 2 8 0a, For example, it has a structure in which two elastic members such as rubber are laminated. also, Scratch 2 8 0, Driven by the wiper drive motor 2 8 1 , The wiper arm 282 is coupled to the wiper arm 282 by the wiper joint portion 284.  The wiper 280 is disposed on the lower side of the wiper portion support plate 287. The wiper joint portion 284 disposed on the upper side of the wiper portion support plate 287, It is connected to the wiper 280 by a through hole or a notch (none of which is shown) formed in the wiper portion support plate 287. Wiper drive motor 2 8 1, It is fixed to the wiper portion support plate 287. also, As shown in Figure 24, The wiper drive shaft 2 8 1 a is set in such a manner as to pass through the wiper drive motor 281 A pressing portion 281b is provided at one end of the wiper drive shaft 28 1a (the end on the side of the wiper arm 2 82). One end of the wiper arm 282, It is connected by the bolt 2 83. One end of the latch 283 is fixed to the wiper portion support plate 287. also, The other end of the wiper arm 282, It is coupled to the wiper coupling portion 284 through the joint portion 284a.  also, At the wiping joint 284, For example, two through holes 2 8 5 are formed in the vertical direction. Two of the brush drive shafts 286 are inserted into the through holes 28 5 . The two wiper drive shafts 2 8 6, The extensions in the direction perpendicular to the radial direction -44 - 200818138 are arranged flush with each other. Scraper drive shaft 286, Although in Figure 22, 23 and 24(a) are not shown for convenience. But as shown in Figure 24(b), a wiper holding member 2 8 8 that is mounted at a slight C The latching member 2 8 also holds the latch 2 83.  The description of the cleaning mechanism of the present embodiment having the above configuration is as follows. First of all, Once the drive shaft 2 8 1 a is moved to the wiper arm 2 8 2 by the rotation of the wiper drive motor 2 8 1 , Then, the pressing portion 281b of the tip end portion of the wiper drive shaft presses the wiper arm 282 toward the moving direction of the wiper drive 201 1a. By this pressure, The wiper arm 2 8 2 is pivoted as a fulcrum, for example, in a counterclockwise direction. then, With the rotation of the wiping arm 282, The joint portion 284a is coupled to the wiper joint portion 284 of the scraper 282, Is one side of the wiper drive shaft 286, One side moves along the axis 286 in a direction perpendicular to the radial direction. Scratch 2 80, The movement of the wiper joint portion 284 is linearly moved toward the print head 25 0 side in a direction perpendicular to the radial direction.  on the other hand, When the wiper arm 282 is intended to be rotated in the clockwise direction, the elastic member (not shown) such as a spring can be used to restore the rotation. That is, for example, Once the motor is driven by the wiper drive motor 28 1 and turned upside down, The wiper drive shaft 28 1 a is moved toward the side of the wiper arm 282, Then, the pressing portion 281b will leave from the wiping arm 282. The pressing force by 28 1b is applied to the wiping arm 2 82. therefore,  Arm 2 8 2, For example, by the restoring force of the above elastic member, And can be used in the shape of a square,  Work,  And the 28 1 a moving shaft is linearly guided by the brush arm.  Sexually Then force and remember the opposite side of the pressure part of the scraping clock -45- 200818138 ground rotation. in this way, The wiper 2 80 can be moved toward the opposite side of the opposite side of the brush head 250 side. By rotating the drive motor and reverse rotation in this way, The wiper 280 can take the exit of the print head 250 (not shown), It is cleaned with a wiping head 2 80a.  (Configuration and operation of the optical disc device 300 according to the third embodiment) Based on Figure 26 to Figure 30, The configuration and operation of the information recording apparatus 300 according to the third aspect of the present invention will be described. In addition,  A replacement method diagram of the print head 75 0 in the previous optical disc device 700; FIG. 2 is an explanatory diagram of a method of replacing the 305 in the optical disc device 300 according to the embodiment; Figure 2 is a perspective view showing the internal structure of the disk device 300 of the present embodiment; Figure 29 is a plan view showing the internal configuration of the optical disk device 300 of the present embodiment; Fig. 30 is a perspective view showing the configuration of a tray as a loading means in the optical disk device 300 of the embodiment.  First of all, As shown in Figure 26, The previous optical disc device 700 is moved on the radial axis at the print head 75 5 . Therefore, it is possible to move to the front of the device to the front of the components disposed on the chuck (not shown) or the optical pickup (not shown). then, Print head 7 5 0 , The upper cover 712 of the housing 710 of the optical disc device 700 must be removed from the upper portion of the disc device 700. Remove the old print head 75 0 'an print head 7 5 0 ', To replace the print head.  therefore, The upper side of the optical disk unit 7 has a space for the print head. also, If there is no such space, Consider the installation of the optical disc (injection of ink from the ink mark 2). The description of the shape of the print head is described in the print head. Replaced by the radial direction of the side system, Take the new replacement unit 700 -46- 200818138 and pull it out from the front. However, there are usually wiring cables such as power cables or signal cables behind the device. Therefore, it is necessary to unplug the wiring device when the optical disk device 700 is taken out. Not very ideal.  In addition, The description of the configuration of the prior optical disc device has been omitted as described above.  on the other hand, As shown in Figure 27 to Figure 29, In the optical disc device 300 according to the embodiment, The print head 350 is movable at a position offset from the radial axis R. therefore, a chuck 330 or an optical pickup 340 or the like that is disposed on the radial axis R, Does not interfere with the print head 350 Therefore, the print head 350 can be moved to the vicinity of the front panel 3 1 4 of the optical disc device 300. then, Before. An opening (not shown) is provided on the panel 3 14 at a position corresponding to the movement axis P of the printing head 350, and an openable and closable print head replacement cover 3 1 9 is provided in the opening, thereby not even The upper cover 312 of the optical disk unit 3 can be removed, and the replacement of the print head 350 can be performed from the front side of the device. That is, after the print head 350 is moved to the front of the front panel 314 by the print head driving mechanism including the head drive motor 3 60 or the like, as shown in FIG. 27, the print head replacement cover 3 1 9 is opened and taken out. The old print head 350' replaces the new print head 350, whereby the print head 350 can be easily replaced from the front side of the optical disc device 300. Therefore, it is not necessary to reserve the space for replacing the print head above the optical disk device 300 as before. Even if there is no such space, it is not necessary to extract the entire optical disk device 300 from the front. In particular, in the case of an ink jet type print head, it is necessary to repair the head when the head is clogged, or to replace the print head with ink consumption. Therefore, it is possible to replace the print head from the front side of the device -47-200818138. Effective. Further, among the configurations of the optical disk device 300 according to the present embodiment shown in FIG. 27 to FIG. 29, the configuration other than the print head replacement cover 3 1 9 provided on the front surface of the device is the same as that of the first embodiment. Since the configuration of the optical disk device 100 is the same, the description thereof will be omitted. Further, as shown in FIG. 30, in the optical disc device 300 according to the present embodiment, the rear side of the tray 3 20 (the rear panel 3 16 side) is used for maintenance such as the cover 3 72 or the waste ink adsorber 3 74. The components are detachably disposed to the tray 320. By providing the maintenance member such as the cover 3 72 or the waste ink adsorber 3 74 on the tray 320, the ink can be cleaned at the same time and easily when the tray 320 is pulled out for taking out the optical disk 5. service. Therefore, in addition to simplifying the configuration of the optical disk device, the maintenance of the optical disk device can be facilitated, and the convenience of the user can be improved. Even by the detachable arrangement of the maintenance member such as the cover 3 72 or the waste ink adsorber 3 74 to the tray 3 20, the cover 3 72 or the waste ink adsorber 3 can be attached while the tray 320 is being withdrawn. The 74 is disassembled and cleaned, so that the effect of preventing contamination inside the optical disc device can be obtained as compared with the prior art. (Structure and operation of the optical disc device 400 according to the fourth embodiment) Next, a configuration of the optical disc device 400 as the information recording apparatus according to the fourth embodiment of the present invention will be described with reference to Figs. 31 to 35. Fig. 31 is a perspective view showing the internal structure of the optical disc device 400 according to the fourth embodiment of the present invention, and Fig. 3 is a main part of the optical disc device 4 0 0 - 48 - 200818138 shown in Fig. 31. 3 is a plan view showing the internal structure of the disc device 400; the optical disc device 400 is viewed from the lower side, and the optical disc device 1 〇〇, 200 described above is in the form of the above optical disc device. The longitudinal direction of the discharge portion is the following problem with the print radial axis R or the radial axis R. That is, if the print width is effectively used in the longitudinal direction R of the print head or in the direction parallel to the radial axis R, the area of the print area at the time of printing is different from each other, and the inner side is smaller than the outer circumference side. There is such a problem without printing and proofing. Further, when the print head is disposed in the longitudinal direction of the print head in the direction of the radial axis R, and is parallel to the movable direction of the print head, it is necessary to rotate the disc while rotating the disc while performing the printing brush. It takes a long time for the action, that is, the relevant text information to be printed, and the problem of the information recording device is also detrimental. Further, in the case where the longitudinal direction of the print head is the same, the light pattern 34 described in the embodiment of the figure which is caused by the rotation of the optical disk is the same as the oblique view of the embodiment. 700, or the first to the third and the third, because the movable direction (ie, the direction) of the print head brush head is uniform, thereby generating a radial axis movable with the print head, although the one-step printing circumference side When the area of the printing area at the time of printing and the side of the inner circumference side is positive, the image point density is caused to be on the radial axis R or parallel, and the long side of the printing head is necessary for label printing. Therefore, when the label printing is performed to simply print the inside of the optical disc recording material, the user convenience is also required, so that the movable direction of the printing head is consistent with the wind, and the ink ejected from the printing head -49-200818138 is caused. When the ink becomes dry or the viscosity is increased, the ink concentration at the beginning of the ink starts to become thicker. Therefore, it is easy to cause unevenness along the movable line of the printing head at the printing start position, and the surrounding portion of the printing start place is conspicuous. The problem also exists. Therefore, in the optical disk device 400 according to the present embodiment, in order to solve the above problem, the print head is movable in a direction parallel to the radial axis at an offset position deviated from the center of rotation of the optical disk. The print head is arranged such that the longitudinal direction of the print head is perpendicular to the radial axis. Hereinafter, the configuration of the optical disc device 400 will be described in detail. The optical disc device 400 according to the present embodiment is inserted into the optical disc 5 as an information recording medium, and can perform label printing on the label surface of the inserted optical disc 5. The optical disc device 400 is mainly provided with an optical disc drive for recording and reproducing data using the optical disc 5. The portion D4 is a label printing portion L4 that is printed on the label side (printing surface) side opposite to the data recording surface of the optical disc 5, that is, on the upper portion of the optical disk drive unit D4. The optical disk drive unit D4 mainly has a front panel 414, a rear panel 416, and a tray 420 that is movably disposed by a predetermined loading mechanism in a field surrounded by the two side panels 4 18 and 418. And a chuck 430 provided above the center portion of the disc loading portion (not shown) of the tray 420; and a tray 420 provided below the tray 420 (on the data recording surface side of the optical disc 5 inserted into the optical disc device 400) An optical pickup 440 as an information recording means. In addition, the configuration and operation of the optical disk drive unit D4 of the optical disk device 400 according to the first embodiment are the same as those of the optical disk drive unit D1 of the optical disk drive 100 according to the first embodiment. The explanation of -50-200818138 is omitted here. The label printing portion L4 mainly includes: a print head 405; and a print head movement required to move the printing head 45 0 in a radial direction parallel to the optical disc 5 at a position deviated from the center of rotation of the optical disc 5 Means; and a print head maintenance means for closing or cleaning the print head 450. The print head 45 0 is configured to be disposed on the opposite side of the optical pickup 440 with respect to the optical disk 5 (on the label surface side of the optical disk 5), and is offset from the radial axis R by a position (offset) parallel to Move in the radial direction (on the x-axis of Figure 33). Further, on the lower surface side of the print head 450 (the label surface side of the optical disc 5), the ink discharge portion 4500 is provided, and the print head 450 is offset (offset) from the radial axis R. The label is printed on the label side of the optical disc 5 by moving the P-axis parallel to the radial direction and ejecting the ink from the ink discharge portion 450o to the rotating optical disc 5. Further, the print head 450 is disposed in two fields in which the field including the optical disc 5 is divided along the moving direction of the optical pickup 440 (that is, the radial axis R in the present embodiment). It is preferable to be in the field of the downstream side of the optical pickup 440 with respect to the rotational direction of the optical disk 5, which is the same as the case of the above embodiment. Here, the configuration of the print head 450 according to the present embodiment will be described based on Fig. 35. Further, Fig. 35 is a perspective view showing the configuration of the printing head 450 in the embodiment. As shown in FIG. 35, the print head 450 is, for example, an ink discharge portion 405a that ejects ink toward the label surface of the optical disc 5, and is supplied from the ink tank 415 by passing through the ink tube 451a, which will be described later. The ink that has come in is supplied to the ink supply tube 450b of the printing heads 4500-51 to 200818138, and the connecting portion 450c that connects the ink supply tube 450b to the head main portion 45d, and the printing head main portion 45. The elastic cable 4 5 0 e on the opposite side of the connecting portion 4 50 c of 0 d is formed. The ink ejecting portion 450a is formed on the lower surface side of the connecting portion 450c (opposite side of the label surface of the optical disc 5), for example, by arranging a plurality of nozzles (ink discharge ports) in a predetermined direction. In the present embodiment, the longitudinal direction of the ink discharge portion 450a formed in the plurality of nozzles arranged in the predetermined direction (the predetermined direction in which the plurality of nozzles are disposed) is parallel to the moving direction of the print head 450 (parallel to the radial direction). Direction) The direction of the vertical is the same. Further, the ink supply tube 450b has one end connected to the ink tube 45 1a and the other end connected to the upper surface side (the side opposite to the ink discharge portion 45 0a) of the connecting portion 45 0c. Further, at least a portion of the inside of the connecting portion 450c is hollow, and a flow path through which the ink passes is formed. The print head main body portion 450d is a substantially rectangular plate-shaped member. As described above, one side is connected to the ink supply tube 450b through the connection portion 450c, and the other side is connected to the elastic cable 45 0e for inputting signals. . In the present embodiment, as shown in FIG. 3 and FIG. 34, for example, the ink discharge portion 450a formed by the plurality of nozzles disposed in the direction perpendicular to the radial direction of the optical disc 5 is formed on the lower surface side of the print head 45 0. In the longitudinal direction, the printing head 450 is disposed such that the moving direction of the printing head 450 moving parallel to the P-axis parallel to the radial axis is perpendicular. As a result, as will be described later, since the printing area on the outer peripheral side and the printing area on the inner peripheral side can be made the same, printing correction is not required. Further, since the label 5 is not required to rotate with the optical disc 5, the printing speed can be remarkably improved in simple printing such as characters. -52- 200818138 Even, since the printing start portion is not linear but flat, the unevenness of the tendons at the beginning of printing is less conspicuous. Further, the print head 450 of the present embodiment is configured to be separated from the ink tank 451 in the same manner as in the case of the optical disc device 200 according to the second embodiment, and the position of the ink tank 461 is It is fixed to the front side of the optical disc device 400, and only the print head 450 can be moved in parallel with the radial direction at a position shifted from the center of rotation of the optical disc 5. In the present embodiment, the ink tank 4 5 1 ' has a structure in which ink cartridges of four colors of Y (yellow), M (magenta), C (cyan), and K (black) are arranged, each of which is formed. The ink tubes are connected to the ink tubes 4 5 1 a (4 in total). The print head 450 supplies ink from these ink tubes 45 1 a at the time of label printing. Further, the print head 45 0 is a print head holder 452 having a substantially rectangular parallelepiped shape and held from above. In the print head holder 452, two head lifting shafts 452a are provided, and the two head lifting shafts 452a are two through holes 4 5 4 formed in a slightly T-shaped head supporting plate 4 5 4 . a fitting, the upper part is fixed by a fixing screw (not shown). By using the head lifting shaft 4 5 2a, the vertical movement of the printing head 450 can be guided. The lower side of the head support plate 4 54 is attached with a head drive bearing member 45 6 extending to the left and right (the direction perpendicular to the radial direction), and the left and right sides of the head drive bearing member 456 are respectively provided. Bearing (linear bearing) 4 5 6 a. The bearing 4 5 6a penetrates in the parallel direction in the radial direction, and is provided with two head drives arranged in parallel (parallel to the radial direction) so as to be inserted through the inner circumference of the bearing 465 a The two-53-200818138 ends of the shaft 4 5 7. 2 head drive shaft 4 5 7 are supported by the same head drive shaft 4 5 8 . The detailed configuration of the print head holder 452 is the same as that of the second embodiment, and thus the description thereof is omitted. The print head moving means is mainly a head drive motor 460, a ball screw 462 coupled to the head drive motor 460, a ball nut 464 inserted by the ball screw 462, and a ball nut 464 and a head drive bearing unit. The connecting member 466 to be connected to the 456, the ball screw supporting member 468 provided in the middle of the ball screw 464, and the limit sensors 491 and 494 are formed. The head drive motor 460 rotates the ball screw 462 by its power. The ball screw 462 is extended in a direction parallel to the radial direction. The ball nut 464 is configured to be movable in a parallel direction in the radial direction by the rotation of the ball screw 462. The coupling member 466 connects the ball nut 466 to the head driving bearing member 456, and the head driving bearing member 456 can be deviated from the center of rotation of the optical disk 5 in accordance with the movement of the ball nut 464. The position of (offset) moves in the parallel direction of the radial direction. The ball screw support member 4 6 8 » is a member that supports the ball screw 4 6 2 ' is a ball screw support plate 468A, and a ball screw support unit (not shown) having a ball screw support unit 4 6 8 B, 4 6 8 C Made into. In the present embodiment, the ball screw support units 4 6 8 B and 46 8 C are integrally formed. The ball screw 4 6 2 is inserted into the ball screw support unit 4 6 8 B and 4 6 8 C via a bearing, and is joined by a nut or the like (not shown). Further, in the optical disc device 400 according to the present embodiment, the movement of the print head -54 - 200818138 450 in the radial direction can be controlled by, for example, the limit sensor 491 or the like. Specifically, the limit sensor 49 1 is, for example, a light sensor configured as a font, and includes a light-emitting element and a light-receiving element (the light-emitting element and the light-receiving element are not shown to face each other, and are emitted from the light-emitting element, and are attached to In the vertical direction, the light receiving element is received by the concave portion 491a. On the other hand, the connecting member 466 of the printing head moving means is provided with the light shielding plate 492 for the sensor, and is provided with a substantially L-shaped light shielding plate support 493. The installation position of the limit sensor 491 is the same as that of the above-described embodiment, and thus detailed description thereof will be omitted. The print head maintenance means, although not shown in Fig. 31, is provided with a cover 472 as shown in Fig. 34. And the waste ink adsorber 474 covers the accommodating portion 470. The closing cover 472 is for suppressing the dry printing standby of the printing head, and the ink discharging portion 450a of the printing head 45 0 is covered by the 472. Further, the waste ink adsorber 474, For example, in order to prevent a printing error such as spitting of the discharge portion 450a and the ink is not generated, air is not mixed into the printing head 450 to perform air ejection (the ink is not printed from the ink discharge portion 45 0a with the label printing). The cover accommodating portion 470 in which the 472 and the waste ink adsorber 474 are housed is disposed on the side opposite to the optical disk 400 on the side opposite to the discharge side (the exit side) of the optical disk 5 (the rear panel 416 side) Here, the print head 450 does not run on the radial axis, so the cover accommodating portion 470 including the cover 472 and the waste ink adsorber 474 is also offset (offset) from the radial axis. Therefore, the light which is made possible by miniaturizing the light to be placed in the optical disk package according to the first embodiment is slightly C)°. The limit component is then closed by 32~, in the case where the closed lid ink is closed and the device is closed. The same is true for the disc-mounted device -55-100 200818138. Further, as shown in FIG. 34, the optical disk device 400 is an example of a cleaning mechanism of the ink discharge portion 450a of the print head 450, and includes a wiper 480 supported by the wiper portion support plate 487. The tip end portion of the wiper 480 is provided with a wiper head 480a as shown in FIG. The other configuration or operation of the wiper 480 is the same as that in the second embodiment, and thus detailed description thereof will be omitted. Although the configuration of the optical disc device 400 has been described above, the operation of the label printing portion L 4 having the optical disc device 400 having the above configuration will be described with reference to Figs. 36, 37A and 37B. Here, FIG. 36 is an explanatory diagram of an example of the movement of the print head at the time of label printing; (a) when printing is performed by the previous print head 750, and (b) is the first embodiment of the present invention. When the print head 150 is printed, (c) is the case when the print head 450 described in the embodiment is printed. Further, Fig. 37A and Fig. 3B are explanatory views showing the areas of the printing areas when the outer peripheral side of the optical disc 5 is printed and the inner peripheral side is printed. In the following description, the same operations as those of the optical disc devices 100, 200, and 300 described in the first to third embodiments will be omitted. In the following description, an example of a disc device in which the print head is moved at a position offset from the center of rotation of the disc is described as an example of the optical disc device 1 according to the first embodiment. However, the same applies to the second and third embodiments. As described above, in the optical disk device 700 of the prior art, or the optical disk device 1 or the like according to the first embodiment, the longitudinal direction of the ink discharge portions 75 0a and 150a of the print heads 750 and 150 is aligned with the printing. When the heads 750 and 150 are movable on the radial axis of the drive-56 - 200818138 or in the direction parallel to the radial axis, the area of the printed area at the time of printing on the outer peripheral side and the inner peripheral side is different from each other. side. First, as shown in Fig. 36 (a), in the conventional optical disk device, since the print head 705 moves on the radial axis, the width is once (in the present embodiment, the printing is performed in one step). When the width in the area direction is the same, the area to be printed in one step (in this embodiment, the ink is discharged once) is smaller toward the disc side. Therefore, when the timings of the ink discharge are the same, the printing density becomes higher toward the inner peripheral side, and the printing near the inner circumference of the optical disk 5 becomes denser, but the printing density in the vicinity of the outer periphery is deteriorated. Here, there is a need to make the printing density near the inner periphery smaller than the outer periphery, so that the dot density becomes equal. In other words, in the configuration of the prior art, the performance of the print head 75 0 cannot be fully exerted, and as shown in Fig. 36 (b), in the optical disk device 1 of the first embodiment of the present invention, The print head 150 is shifted from the center of the optical disc 5 and moved in the direction parallel to the radial axis at the offset position. However, in the same manner as the previous optical disc device 700, the print head 150 is printed in one step, and is passed to the inner circumference of the optical disc 5. The smaller the side. Further, the narrower the printing width toward the inner peripheral side, the extent of the reduction of the area is more remarkable than in the case of the prior apparatus 700. Therefore, in this case, the printing density near the inner circumference is made slightly smaller than the vicinity of the outer circumference, so that the dot density becomes equal. On the other hand, as shown in Fig. 3 6 (c), in the printed radial state of the printed printing 700 of the present embodiment, the inner peripheral optical disc 5 has a slightly thinner brush density. In the rotation, the disc of the brush is required to be corrected. The light-57-200818138 disc device 400 has a print head 45 which is shifted from the center of rotation of the disc 5 and is radially at the offset position. The axis is moved in the parallel direction, and the longitudinal direction of the ink discharge portion 450a of the print head 450 is perpendicular to the radial axis (the moving direction of the print head 450). Therefore, in this case, the printing width of the primary printing is more toward the inner peripheral side. The area where printing is performed in one step is equal to the inner circumference side and the outer circumference side of the optical disc 5. Here, the reason why the area of the area printed by the one-step step in the optical disk device 4 is equal is described with reference to Figs. 37A and 37B. Before explaining this reason, the inventors of the present invention have calculated an example of the area printed by one step, which is shown in Table 1 below. -58- 200818138 [Table 1] Print head width mm Offset mm Outer radius mm Inner radius mm Printed area mm2 Area ratio % Casel 13. 6 0. 0 When the print head is on the 丨 to the axis Areal 58. 0 44. 4 4,375 45. 4 Area2 44. 4 30. 8 3,213 33. 3 Area3 30. 8 17. 2 2,051 21. 3 printing area 40. 8 9,639 100. 0 Case2 13. 6 20. 0 The direction of the print head is parallel to the radial 轺 ί when Areal 58. 0 45. 4 4?082 43. 8 Area2 45. 4 33. 8 2,905 31. 2 Area3 33. 8 24. 2 1,743 18. 7 Area4 24. 2 20. 0 581 6. 2 printing area 38. 0 9?312 100. 0 Case3 13. 6 20. 0 The direction of the print head is perpendicular to the radial 轺 (1) Areal 57. 6 50. 9 2?290 25. 0 Area2 50. 9 43. 1 2,290 25. 0 Area3 43. 1 33. 6 2?290 25. 0 Area4 33. 6 20. 0 2,290 25. 0 printing area 37. 6, 9,160 100. 0 Case4 17. 5 20. 0 The direction of the print head is perpendicular to the radial 轺 pickled (2) Areal 58. 5 49. 1 3?161 33. 3 Area2 49. 1 37. 5 3,161 33. 3 Area3 37. 5 20. 0 3,161 33. 3 printing area 38. 47 9,484 100. 0 Case5 10. 0 20. 0 The direction of the print head is perpendicular to the radial 轺 (3) Areal 58. 3 53. 9 1,571 16. 7 Area2 53. 9 49. 0 1?571 16. 7 Area3 49. 0 43. 6 1,571 16. 7 Area4 43. 6 37. 4 1?571 16. 7 Area5 37. 4 30. 0 1?571 16. 7 Area6 30. 0 20. 0 1?571 16. 7 printing area 38. 31 9,425 100. 0 - 59 - 200818138 In Table 1, the easel is equivalent to the previous optical disk device 700 (see Fig. 36 (a)), and the case 2 corresponds to the case of the optical disk device 1 according to the first embodiment of the present invention. In the example (see FIG. 3 6 (b)), cases 3 to 5 correspond to the case of the optical disk device 400 according to the present embodiment (see FIG. 36(c) for the reference case 3). In the cases 3 to 5, as described in Table 1, the width (mm) of the longitudinal direction of the printing head 450 is changed, and the ink discharge portion is formed by arranging the ink discharge nozzles of about 300 to 400 in a line. Further, the offset amount is easel, 2 is the distance (mm) from the radial axis of the optical disc 5 to the center of the print head 450, and is the radial axis of the optical disc 5 in cases 3 to 5. The distance (mm) from the tangential direction to the left end (the end closer to the radial axis) of the ink discharge portion 45 0a. As shown in Table 1, in the case of c a s e 1 , the area ratio of the printed area is Areal : Area2 : Area3 = 45. 4[%] : 33·3[%] : 21·3[%]; In the case of case2, Bay [J is Areal : Area2: Area3 : Area4 = 43·8[%] : 31·2[%] : 18. 7[%] : 6·2[%]. As described above, in the case of easel and case2, the area of the printing area is smaller toward the inner peripheral side of the optical disk 5, and particularly in the case of c a s e 2 , the amount of reduction in the area of the printing area is particularly remarkable. On the other hand, in the case of cases 3 to 5, since the width of the printing head 450 is different, the number of printings (the number of printing areas) is also different, but in either case, the area of the printing area is within the optical disk 5. Both the circumferential side and the outer peripheral side are unchanged, and all printed areas are the same area. Therefore, in the case of cases 3 to 5, as long as the discharge timing of the inks is the same, uniform printing density can be achieved even without image point correction. -60- 200818138 To verify this in theory, first, as shown in Figure 37A, if the area printed in the first printing is A1, the area printed in the second printing is A2 ( Figure 3 7 is a thick solid line showing the position of the print head 450 when the second printing is performed) ' as shown in Fig. 37A, 'the offset amount of the print head 450 is a, the print head 450 The printing width of the second printing is b', and the position of the printing head A1 in the radial direction is k when the second printing is performed. The area sa 1 of the printing area A1 is: SAi=;rx(a +b) 2 - π xa2 Further, the area SA2 of the printing area A2 is: SA2=^x(a+b+c) 2-7rx(a+b) 2 · · · (1) Then, according to Pydago Las's theorem, a2+k2= (a+b) 2 *··(2) (a+b) 2+k2= (a+b+c) 2 · · · (3) holds, so if we 2), (3) Substituting into equation (1) 'is: SA2r=r 7ΓΧ (a+b+c) 2-7rx(a+b) = ;rx( (a+b) 2+k2) - 7TX( a + k ) =7Γ x ( a + b ) 2- π xa2 =SAi Similarly, as shown in Fig. 37B, the area printed in the third printing is A3, and the printing width of the third printing is d, print head 4 5 when printing is performed When the radial direction position of 0 is z, the area S a 3 of the printing area A 3 is

Sas^ (a+b+c+d) 2- κ x (a+b+c) ··· · (4) Again, according to Pythagorean theorem, -61 - 200818138 a2 + z2 = ( a + b + c ) 2 · · · (5) (a+b) 2+z2= (a+b+c+d) 2 · · · (6) is established, so if equations (5) and (6) are substituted Equation (4) is:

Sa3=^x (a+b+c+d) 2-7rx (a+b+c) 2 =π x ( ( a + b ) 2 + z2 ) - ττ χ ( a2 + z2 ) = ^x(a +b) 2 - -7Γ x a2 Two SA1 The following analogy, if it is assumed that the printing area for the nth printing is An, then SAi = SA2 = SA3 II · · = SAn This fact is proved. Thus, by making the longitudinal direction of the ink discharge portion 405 a of the print head 450 into the vertical direction in which the print head 450 moves, the area of the area printed in one step can be made identical. Then, since the areas of the printing areas are all equal, the printing density is the same as long as the ejection timing of the inks is the same. That is, in the case of the optical disk device 400 according to the present embodiment, it is different from the previous embodiment or the above-described embodiment, and uniform printing can be performed without performing image point correction. Therefore, in the present embodiment, the performance of the print head 450 can be fully utilized. Further, if the discharge timing of the ink is adjusted in accordance with the area ratio of the printing area, that is, the optical disc device 100 (Fig. 36 (a)) or the optical disc device 100 of the first embodiment ( In Fig. 36 (b)) and the like, when the discharge on the outer peripheral side of the optical disk 5 is delayed with the printing area, even if the image point correction (density correction) is not performed, the uniform printing can be performed - 62 - 200818138 . However, in order to fully exhibit the performance of the print head, the fastest ink discharge timing is required. From this point of view, the optical disk device 400 (Fig. 36 (c)) according to the present embodiment is most preferable. Next, the embodiment will be described based on FIG. 3 . In the optical disc device 400, the effect of suppressing the unevenness of the tendons on the printing start position at the time of label printing is performed. In addition, Fig. 3 is a comparative photograph of a state example (b) of the label surface after label printing in the present embodiment and a state (a) of the label surface after label printing in the first embodiment of the present invention.  As shown in Figure 3 8 (a), When the optical disc device 1 according to the first embodiment, in which the longitudinal direction of the printing head coincides with the moving direction of the printing head, is used for label printing, It can be seen that at the beginning of printing, Along the line moved by the print head 150, Will produce uneven tendons. This is because of the influence of the wind generated by the rotation of the optical disc 5, The ink ejected from the ink ejecting portion 150a of the printing head 150 is dried or the viscosity is increased. This causes the ink concentration at the start of ink ejection to become thicker. on the other hand, As shown in Figure 3 8 (b), When label printing is performed using the optical disk device 400 of the present embodiment in which the longitudinal direction of the printing head is perpendicular to the moving direction of the printing head, Can be seen at the beginning of the printing, The unevenness of the tendons becomes inconspicuous. This is because 'the direction of the long side of the print head 450 is perpendicular to the direction in which the print head 450 moves, Therefore, the beginning of printing is different from the case of Figure 38 (a). Not in a straight line, But in a plane,  The ink with increased viscosity can be dispersed.  also, The optical disc device 400 according to the embodiment, The discharge operation of the optical disc 5 caused by the tray 42 0 for inserting the optical disc 5 into the discharge device of the optical disc device 400 can also be utilized. To print labels. E.g,  - 63- 200818138 As shown in Figure 39, In the case of printing only relevant text information of the contents of the material recorded on the disc 5, When the optical disc 5 is ejected from the front side of the optical disc device 400 (Fig. 39 indicates the loading direction of the optical disc 5), Controlling the print head 450 to eject ink to print text information, The printing result as shown in Fig. 39 can be obtained easily and at high speed.  That is, in this embodiment, Since the print head 45 0 is disposed at a position offset from the center of the optical disc 5, Therefore, the tray 410 is for discharging the optical disc 5 to the outside of the optical disc device 400. And moving the optical disc 5 toward its outer circumference, Thereby, the print head 450 can be relatively moved to the optical disc 5. Therefore, If the print head 450 is printed on the optical disc 5 once, the information such as characters or graphics can be printed. The label printing can be performed by the discharge operation of the optical disc 5. In addition, On the occasion of the discharge of the disc 5, Whether or not the print head 4500 is activated, As long as the print head 450 is moved in the opposite direction to the direction in which the optical disc 5 is discharged, Even if the print head 4500 is not operated, It can also be printed at high speed. In other words, When printing on the label side of the disc 5, Although it is necessary to convert the printed materials and then print them, But for example, when you only want to print text, Then, at the timing when the optical disc 5 is discharged from the optical disc device 400, Controlling the discharge of the print head 450 The printing result as shown in Fig. 39 can be obtained easily and at high speed.  As explained above, According to the optical disc device 400 of the embodiment, Then the print head 4500 does not pass through the center of rotation of the disc 5, The longitudinal direction of the print head 450 is configured to be perpendicular to its movable axis, Therefore, the printing area of each step can be made uniform or nearly uniform. Therefore, the following effects can be obtained -64- 200818138 (1) If the timing of the ink ejection from the print head is the same, The printing density of each printing area is the same; (2) The label printing can be performed in a uniform or approximate state even without performing concentration correction; (3) The performance of the print head can be fully developed.  also, According to the optical disc device 400 of the embodiment, Then, the longitudinal direction of the ink discharge portion 450a of the printing head 450 and the movable axis of the printing head 450 are perpendicular. Therefore, the following effects can be obtained: (1) Improve the linear ribs on the printing start site, It makes it less noticeable than other parts.  even, Since the longitudinal direction of the ink ejecting portion 450a of the printing head 450 is perpendicular to the moving direction of loading of the optical disc 5, Therefore, it is possible to print simple materials such as characters by using the discharge operation of the disc. therefore, When there is less printing material, Can significantly reduce printing time, Increase user convenience,  This effect can be obtained.  In addition, The optical disc device 400 according to the embodiment, The system is not limited to the above examples. For example, it is also conceivable that the shape of the print head 450 is different from the above example, The cover 472 or the waste ink adsorber 474 is in the form of other shapes, etc. Various changes can be made.  (Configuration and Operation of Optical Disc Device 500 in the Fifth Embodiment) Next, Based on Figure 40, A configuration of an optical disk device 500 which is an audio recording device according to a fifth embodiment of the present invention will be described.

For example, the movement distance of the print head 550 is once, Is equal to the maximum print width of the print head 5 5 、, 本实-70- 200818138 In the form of the ink, the l/n (η is a natural number) or more of the ink discharge portion is Although the composition of the optical disc device 500 is based on FIG. 41, Figure 42 and Figure 43, The operation at the time of label printing having the above configuration 500 will be described. In addition, Figure 41 is an explanatory diagram of the operation of printing in the brush mode, (a) when the disc device 700 is used, (b) A case where the optical disk device 500 of the fifth embodiment of the present invention is used. Figure 42 is an explanatory diagram of the operation of printing in multiple lines. (a) when using the previous 7〇〇, (b) A case where the disk device 500 of the fifth embodiment of the present invention is used. Fig. 43 is a comparative photograph showing a state example of the label side after single printing and a state example of the label printing surface by multiple printing. also, In the following description,  The optical disc device 100 according to the third embodiment, 200 and action, The duplicate description is omitted.  First of all, Description Label printing in single print mode The so-called single print mode, As mentioned above, Is to print the same field on the disc 5 media once, More specifically, as shown in 41 (c), The printing controller 5 70 is moved by the printing head once and exactly with the printing width (the width of the ink discharging portion (transfer amount), To print (1 (1) to (3 1 step to 3 step). therefore, 1 image point is printed. Figure 4 1 (a) shows that the print head is moving up on the radial axis; Figure 41 (b) shows the position of the print head at a position offset from the disc 5, When moving in a direction parallel to the radial axis, However, the assembled optical disc is printed in the same manner as the above-mentioned first one by the label printed on the optical disc described in the optical disc device in the printing mode of the previous optical printing mode.  For information records, As shown in the figure, Let the degree be the same distance) means the first (J 1 times).  The situation of moving time is the case of turning to the center. Ink -71 - 200818138 On the water spit out, For example, there are 30 to 400 ink ejection nozzles side by side. If the manufacturing is not uniform, the arrangement of the nozzles is uneven. It will result in uneven color. therefore, When printing a single time, Regardless of the above (a), (b) which situation, The performance difference of the nozzle is directly related to the image quality. As shown in Figure 43 (a), Concentric circular unevenness is likely to occur on the disc 5. Furthermore, because of the repeated influence of the nozzle performance difference of each step, the printing is greatly affected. Concentricity of the tendons will be more conspicuous.  then, Explain the situation when label printing is performed in the multiple printing mode.  The so-called multiple printing mode, As mentioned above, It is a plurality of (two or more) prints in the same field on the information recording medium such as the optical disc 5, More physically, As shown in Figure 42 (c), The printing controller 5 70 is a printing step of one time. The print head is moved by exactly the same distance (transfer amount) as 1 / η (the natural number of η system 2 or more) of the printing width (the width of the ink discharge portion), For printing (the (1) to (6) lines indicate the first step to the sixth step). therefore, One image point is printed twice or more. In addition, As shown in Figure 42 (c), η = 2, that is, The case where the print head is moved exactly 1 /2 of the width of the Moss soil out of each step.  Figure 42 (a) shows the situation when the print head is moving on the radial axis; Figure 42 (b) shows that the print head is offset from the center of rotation of the optical disc 5, The case when moving in a direction parallel to the radial axis. The arrangement of the nozzles is not uniform due to manufacturing errors. This will involve problems with uneven color. It is the same as in the case of single printing. but, At the time of multiple printing, the print head is successively pushed by 1 / η in a single printing step by one step (for example, 1 /2 in the present embodiment). Therefore, on the same area (for example, 1 pixel) of -72- 200818138 on the disc 5, Printing can be performed by using two or more nozzles (two in the present embodiment). therefore, The effect of nozzle performance differences, It is not easy to be noticeable when printing in a single time. As shown in Figure 43 (b), The concentric unevenness on the disc 5 is less conspicuous (the unevenness is averaged). That is, Label printing with multiple prints, It is possible to print images of higher quality. even, If the amount of movement of the print head of one step is reduced to 1/4 of that of a single print, 1/8, Then, since the number of nozzles for printing the same field (for example, one pixel) on the optical disc 5 can be increased to four, 8, Therefore, the influence of nozzle performance difference is more difficult to highlight (the allowable range of nozzle performance difference becomes wider), Prints higher quality images. even, Not only can you improve the quality of the printed image, Can also improve yield, It is even possible to reduce costs.  only, As shown in Figure 4 2 (a), When the print head is moving on the radial axis, Since the print head system interferes with components such as the chuck, Therefore, it is not possible to sufficiently perform multiple printing on the inner peripheral side of the optical disc 5. therefore, E.g,  As shown in the enlarged photo in Figure 4 2 ( a ), The outer peripheral side is a multi-printing area that can be multi-printed. The inside is due to interference with components such as the chuck.  Therefore, it becomes a single printing area where only one printing can be performed (that is, only one printing can be performed). A label-free printing area that is completely unprintable. On the other hand, in the case where the print head is shifted from the center of rotation of the optical disk 5 and moved in the direction parallel to the radial axis at the offset position, Since the print head moves away from components such as chucks, Therefore, as shown in Figure 4 2 (b), Multiple printing can be performed up to the vicinity of the center of the inner circumference side of the optical disc 5.  As explained above, According to the optical disc device of the embodiment - 73- 200818138 4 00, Then the print head does not pass through the center of rotation of the disc. Moreover, the amount of movement of the print head is made smaller than the width of the ink discharge portion to perform multiple printing. With this, Compared to the previous one, Added printable area, It can be easily printed not only until the inner circumference of the disc. It can also improve the image quality of the printed image. Can get these effects.  also, As mentioned above, In the previous single mode printing, Will cause unevenness of the ribs and degrade the quality of the printed image. But in addition to this unevenness of the tendons, E.g, When repeating a specific pattern for printing, In the case of single mode printing, The nozzles used are often the same one, It is easy to cause nozzle deterioration. on the contrary, No nozzles, There may also be errors caused by dry ink blocking and the like. There is such a problem. especially, Using the hot inkjet method, It is easy to cause deterioration of the nozzle. In this regard, When printing in multi mode, Since the nozzles are used on average, Therefore, these problems are not easy to occur.  even, When printing a disc, Compared to the usual printing of paper, The printed matter, that is, the disc (the label) moves faster. Relatively speaking, the printing load of the nozzle is high. also, Easy to be affected by the wind generated by the disc, It is easy to cause the ink to dry and block the nozzle. These problems also exist.  In contrast, In the case of multi-mode printing, Since the frequency of use of each nozzle can be reduced, Therefore, the printing load can be reduced. Preventing the ink from drying and blocking the nozzle is more effective.  also, In the case of a typical inkjet printer, Since the paper of the printed matter at the time of printing is fixed, Only the print head reciprocates, Therefore, the relative speed of the print head to the printed matter can only be raised to some extent. but, When the label of the disc is printed, Although an encoder or the like is used to reduce the rotation speed, However, in the case of printing in the case of reading data, for example, in the embodiment of the present invention, Can be about 1 0~1 5 times, Therefore, the effect of multi-mode printing is great.  Further, the optical disk device 400 of the present embodiment, The system is not limited to the above examples. For example, it is also conceivable that the amount of movement in one step of the print head is set to be different from the above example. Or when there is no single printing mode and only multiple printing modes, etc. Various changes can be made.  (Configuration and Operation of Optical Disc Device 600 in the Sixth Embodiment) Next, Based on Figure 44 to Figure 47, The configuration of the optical disk device 600 as the information recording device described in the sixth embodiment of the present invention will be described.
